Bio
Asma Fallah is a Ph.D. candidate in the Electrical and Systems Engineering Department at the University of Pennsylvania, working in Prof. Nader Engheta’s group. She earned her Master’s degree from the University of Pennsylvania in 2020, after receiving her Bachelor’s degree in Electrical Engineering from the University of Tehran, Iran, in 2016. Her research interests include novel optical wave-matter interactions, with a focus on metamaterials, metasurfaces, plasmonic optics, and the electromagnetic response of time-varying structures. Her work has been published in several prestigious journals, and she was invited to present her eresearch at the Plasmonics and Nanophotonics Gordon Research Seminar in 2024. She also received an ONR/NSF grant to attend the Metamaterials 2021 Congress and the Euprometa School on ‘Emerging Concepts and Anomalies in Light Scattering.’

Four-dimensional Wave-Matter Interaction
In recent years, the study of wave interactions with four-dimensional (4D) material platforms-where material parameters change with time while waves are present-has opened new avenues in the manipulation of electromagnetic waves. This field has led to a range of innovative applications, such as temporal aiming, time reversal, holography, pulse shaping, energy transformation, and nonreciprocity. My research specifically explores the temporal dynamics of electromagnetic waves within various geometries, where the plasma frequency of the dispersive medium undergoes abrupt changes over time. By examining these scenarios, my work provides valuable insights into how electromagnetic waves behave during complex media transitions, revealing new opportunities for controlling wave propagation in both space and time. These findings have potential applications in developing time metamaterials, enhancing communication systems, and optimizing pulse shaping techniques for advanced signal processing.
